CAR SEAT. P

Application filed August. 12, 192i. s ri l 491,677.

To all whom it may concern." j a Be it known that I, EDWARDC. LANG,citizen of the United States, residing at Melrose, in the county ofMiddlesex and State of Massachusetts, have invented new. and usefulImprovements in Car Seats, of which the following is a specification.

This invention relates to a car seat, the seat section of which issupported by a suitable rest, and is adapted to be swung upwardly fromits operative positionfon the' rest to a position upturned against theback section.

The chief object of the invention is to provide a loose connectionbetween the seat section and the rest, of extreme simplicity, and freefrom articulated hinge joints, said, connection being organized topermit a swinging movement of the seat sectionon a shifting center, sothat it may be upturned against the back section without injuriouscontact with the latter during the operation, and to maintain a looseanchoring engagement between the rest and the seat;

' section, whereby unintentional 0r accidental separation of the seatsection from rest is prevented.

Other objects are to provide improved means for preventing removal ofthe seat. section from the rest when in its upturned position; forpermitting removal of the seat section only when the latter isapredetermined position; and for preventing downward tipping of the seatsection from its operative position when the seat section; projects.considerably forward from the rest. j r

The invention is embodied in the improvements which I will'now proceedto describe. and claim. j 1

may he of. ,a ny suitable construction, and

may, ormay not include ayieldingly sup ported flexible top 13. I

.F gure 1 shows a suitable form of fixed FFEC portions of a reversiblesupporting means, .which may include the usual[ :outer and inner endmembers 14: and 15 and suitable intermediate connecting membersflti.Theseat section is directly supported by rests 19, which in this caseare the rest-and formed-on a fixed metal end.-

piece 20', to which-the back section is attached. 1The seat section andthe supporting-means are provided with loose connection elements havingmeans for permitting fined, and one of a plurality ofsimilaraswinging'movement of the seat section,1on I ashifting center, from itsoperativeposition shown'by'full l nes, to its upturned position,-

upturned against the back section, as shownby dotted lines at the leftof Figure 2, one

of said elements being the rest 19.

I Said connection elements also have means tion from the rest when theseat section is in its upturned position, and means for permittingseparation of the seat section from the rest when the seat section ismoved from its upturned position. v

Said connection elements include in ad dition to the rest 19, an angularear 18, rigidly secured to the rear portion of the seat section,and'projecting from the bottom of the latter, the outer end of the rearbeing provided with a head or enlargement 18. The rest 19 may be formedin any suitable way to constitute another element of a loose connectionpermitting a swinging movement of the seat section ona shifting centerand maintaining a loose anchoring engagement between the rest and theear,'thenature of said engagement being such that the seat section isnot liable to be unintentionally or accidentally separated fromthe rest.Ashere shown, the rest is provided with a longitudinal slot 23, formedt'oreceive the ear 1S, and provided with an enlargement 22 at one end.When the seat section is held edgewise in the right-hand dotted lineposition of Figure 2, the head 18 is passed through the enlargement 22.The seat section is then swung downward and moved edgewise inward to thefull lineposition shown by Figure 2. A portion of theangular ear 18 isthus caused to project under a portion 19 of the rest at the inner 'endof I the slot 23, said portion constituting a stop which1 prevents theinner edge ofthe seat sectlon from being swung upwardb'y downwardpressure on the forward edge' portion of the seat section, the latterbeingformed to project considerably forward from the rest 19. v

Thes lot 23 and ear 18 now permit a swinging movement of the seatsectiongon a shifting center, from its operative to its upturnedposition, the seat section, when folded, being inclined backward andhaving its center of gravity shifted sufliciently tocause it to remainin the upturned position. The open space under the rest permits the freeswinging of the ear with the seat section. The slot 23 is elongated, sothat when the seat section is upturned, the ear head 18 is under thenarrower portion of the slot, as indicated by Figure 3, so that the earcannot be removed from the rest, removal of the seat section fromthevrest while the seat section is upturned, being thus prevented. Whenthe seat=- section while upturned is moved forward to the the slotenlargement 22, so that the seat section maybe removed from the rest.Edgewise forward movement of the seat section from its operativeposition is prevented by n I stud 25,projecting upward from the rest,for preventing separation or" the xback-secknown type of car seat,having a swinging reversible back section 29.

I do not show the means for inovab'ly supporting the rocker and the backsection,

such means being well understood by those skilled in the art.

The flanges 27 are provided with longitudinal slots 30, havingenlargements 30' at their outer ends, the inner ends of said flangesbeing formed in the raised portions 27?, and the ends having theenlargements in depressed portions 27 of said flanges. The seat section29 is provided with two angular ears 31, each having a head orenlargement 31 The arrangement is such that when the seat is held in theposition indicated by Figure 7, and moved downward, the ears 31 enterthe slots 30, the heads 31 passing through the slot enlargements 30 Whenthe seat section is tipped from the operative position shown by Figure8, to the upturned position shown by Figure 11, one of its arms 31swings out of the corresponding slot 30, the other arm remaining in theother slot, and swinging therein until its head 31 abuts against theraised portiono27 of the rest, and is prevented from being with-,

drawn from the slot, as indicatedby Fig the depressed flange portion 27and against" the back 29, the position of the seat section being suchthat it is not liable man forward.

It will be seen that the loose anchoring connection between the seatsection and the rest is provided by imparting a predeten mined formationto the rest, enablinggthelatterto serve also as a connection element,and by attaching the angular earto the seat section, the expense andcomplicationof articulated hinge joints being eliminated.

I claim: 1. A seat having, in combination, a-pair of res-ts havingupwardly facing upper surfaces forming seats for a movable seat section,and downwardly facing lower surfan faces; supporting means for saidrests forming open spaces below said lower surfaces, said rests havinglongitudinal slots provided with end enlargements; a movable seatsection; angular brackets fixed to the bottom of the seat section andincluding inner portions perpendicular to said bottom, arms extendedfrom said inner portions substantially parallel with said bottom, andtransverse lugs on the rear ends of said arms, adapted to register withsaid enlargements and to be slidably engaged in said spaces with thelower surfaces of the rests, said brackets being removable fro-m saidslots only when the lugs are in a predetermined position below saidenlargement.

2. A car seat having, in combination, a fixed back section, a pivotaland removable seat section, supporting members secured to the loweredges of said back section, and extending forwardly therefrom, saidmembers including inturned flanges constituting rests having upwardlyfacing upper surfaces forming seats for the bottom of the seatsection,and downwardly facing lower surfaces, said rests having longitudinalslots formed at their forward ends with enlargements, and angularsecuring brackets fixed to the bottom of said seat section, andincluding inner portions perpendicular to said bottom, arms rearwardlyextended from said inner portions, substantially parallel with saidbottom, and transverse lugs on the rear ends of said arms, adaptedtoregister with said enlargements, and to be slidably engaged in saidspaces with the lower surfaces of the rests, said brackets beingremovable from said slots only when the lugs are in a predeterminedposition below said enlargements, the arrangement being such that thelugs are below the enlargements only when the rest is in an upturnedposition and spaced forward from the fixed back section.

3. A car seat having in combination, a back section, a pivotal andremovable seat section, rest members secured to the lower edges of saidback section and extending forwardly therefrom, the said rests providedin their forward portions with inturned horizontal flanges havinglongitudinal slots arranged therein, said slots formed at their forwardends with enlargements, securing brackets fixed to said seat section,said brackets having their free ends rearwardly disposed and providedwith transverse lugs adapted to engage said flanges for slidablysecuring the seat to the rests, and prevent tipping of the front end ofthe seat, said seat being removable from the rest when the latter is ina predetermined position relative to said flanges.

i. A seat having in combination a pair of supports, rests secured tosaid supports, said rests being provided with inturned flanges havinglongitudinal slots therein, enlargements formed in end portions of saidslots, a removable seat, brackets provided with vertical and rearwardlyextending arms fixed to said seat, transverse lugs arranged in said armsadapted to register with said enlargements, and to be slidably securedbelow said slots, said brackets being removable from said slots onlywhen the lugs are in a predetermined position below said enlargements.

In testimony whereof I have aflixed my signature.

EDWARD C. LANG.
